Am I having an identity crisis?

I'm mexican but I have very asian features, everyone thinks I'm asian, when I look in the mirror I see an asian male more likely chinese or mongolian. My dad claims mexican too but in his photos he looks Filipino. I'm very confused. Full mexicans call me "chinito" (my username too) and they've said I look chinese to them. When I see full mexicans I feel seperated from them and am tired of having to prove im mexican when i talk to people. When I'm with asians I feel connected with them but also feeling like a "wannabe" because of me not actually being one and only looking like one. What should I do now? Should I have a dna test to see if I'm asian?
